3. Fitting the interior siren:
The interior siren has 2 functions: to provide an audio indication when the alarm is
switched in and out, and to operate as an alarm should there be a break in. An interior
siren has the advantage that the intruder will be WITHIN the noise field, which is almost
unbearable. Mount the interior siren under the dashboard, so that the location of the
siren is not immediately obvious, but will nonetheless produces a loud enough noise.
(The siren can be tested by connecting the red wire to the + terminal and the black wire
to the - terminal of the battery).
WARNING: the siren produces a high level of noise. If it is pointed directly to
your ear or somebody else's it may cause permanent hearing damage.
NOTE: if an external siren is not connected, then the internal siren can also be fitted
under the bonnet. Ensure that the siren is at a slight angle so that water cannot ingress.
4. Fitting the contact switches:
Contact switches have to be fitted if the bonnet or boot are to be protected. They need not
be fitted if the cover concerned is fitted with a light, (however the current consumption
detector should then be checked for correct operation - see further). To protect the bonnet,
the adjustable gold coloured pressure switch can be used. Look for a smooth metal
surface on the periphery of the bonnet and radiator sealing. Drill a 7 mm hole and fix the
contact to it. To protect the boot, look for a smooth metal surface on the periphery of the
boot sealing where the self tapping pressure switch can be mounted. Drill a 6 millimetre
hole and use an 11 mm socket spanner to screw the switch into place. Underneath the
contacts a wire can be connected to the plug.
NOTE: Ensure that the switches are pressed in when the bonnet or boot is closed.
Ensure that the switches make a good contact with the chassis.
5. Fitting the shock detector (complete module):
Fit the shock detector to the chassis in the passenger interior (under the dashboard) or
in the boot.
NOTE: The detector must make a good contact with the chassis or metalwork of the
car, otherwise it will work poorly or not at all. The shock detector may not be fitted
outside or underneath the bonnet as it is not watertight.
6. Fitting the IR receiver module (only for K3512):
Using double sided adhesive tape, mount the receiver module to the ceiling or
underneath the dashboard such that there will be no direct sunlight on the sensor. If you
are not certain about where to put the receiver, then it is best to wait until the entire
alarm system has been fitted so that the receiver can be tested before putting it in a
permanent position.
CONNECTION
The alarm can be connected up in different ways depending on the type of sensors connected
to it. Different combinations of the connectors described below are possible.
